IMPROVEMENT IN FLOCK-CLEANING MACHINES.

Specification forming part of Letters Patent No. 140,684, dated July 8, 1873 application led October 16, 1872.

To all whom it may concern:

Beit known that I, RICHARD H. DAWSON, of Rockville, in the county of Tolland and State of Connecticut, have invented a new and useful Improved Flock-Cleaning Machine, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side eleva-tion. Fig. 2 is a plan View. y

In the process of forming a nap on cloths there are produced what are known as flocks, which are matted together and contain a great number of teazle points. machine for loosening up these flocks, and cleaning out the teazle-points.

The .letter a indicates the frame of the mab is the main shaft, to which power is applied by means of a belt running on the pulley bl. The other pulley b2 is a common loose pulley. Power is communicated to the shaft c bya belt running from the pulley b3 to the pulley c1. The belt d2 communicates power from the pulley b5 to the pulley d1 and shaft d. The belt c2 communicates power from the pulley 114 to the pulley c1 and shaft c. The belt f2 communicates power from the pulley ZG to the pulleys f1 and j', and the belt g2, running from the pulley f, communicates power to the pulley gl and shaft g. The liock is fed to the machine upon the endless apron h, which runs upon the roll h1, and a similar roll upon the shaft g being propelled by the latter. This apron brings the ock up against the brushcylinder c2, which is a cylinder covered with a brush, and revolves in the direction indicated by the arrow. The brush, thus revolving, catches the flock and carries it around upon its surface. lt travels thus but a little way before it comes in contact with the teeth of the comb t, which extends quite across the face of the brush-cylinder, its ends set in the guide .or side boards jj, and so arranged as to be adjustable toward and from the surface of vthe brushcylinder. The effect of the catching ofthe Hock against this comb is to loosen it up and separate the bers. A little further on the flock strikes against a second comb, t1, which is set a little nearer to the face of the My invention is aY brush than the comb t'. In like manner the flock strikes against a third comb, i2, which is set nearer to the brush than the comb t, and by this time the flock is thoroughly loosened up. After passing all these combs the iock is carried against the card-tooth cylinder la, which is covered with .what is known to cloth-makers as card-elothin g. It revolves in the direction indicated by its arrow, but much more slowly than the cylinder c2, so that the ilock catches in the hooks of the card-clothing, while the brush-cylinder c2 brushes out all the teazlepoints. The brush-cylinder Vcontiuues and perfects the operation of brushing out the teazle-points. The ock thus cleared of its teazle-points passes on with the cylinder k till it comes to another brushcylinder, m, which is so'sct that its bristles mesh into the hooks of the cylinder k, thus availing to brush the flock out from the hooks so that it falls down and is conveyed away by the spout a. The cylinders c2 and l are set so that their bristles but just meet or fall a'trifle short of the hooks on the cylinder k. The teeth ofthe comb il are longer that those of the comb t', and those ofthe comb i2 are somewhat longer than those of the comb 1.

I claim as my inventionl. rIhe combination of the rotating brusheylin'der c2 with the overlying stationary combs i t t2, 011e or more, both constructed, arranged, and designed to operate substantially as dcscribed, for the purpose set forth.

2. The combination of the rotary brush-cylinder 2, the overlying combsz' il 2, one or more, and the eardtoothed cylinder k, all constructed, arranged, and designed to operate substantially as and for the purpose set forth.

3. The combination of the brush-cylinder c2, the overlying combs t' t1 t2, on"e or more, the card-toothed cylinder 7o, and the brush-cylindefm, rotating in the same direction with the card-toothed cylinder, the whole constructed, arranged, and designed to operate substantially as and for the purpose set forth.
